Usually, in the actual drilling situation, when the drilling fluid rate is 28~35 L/s, the electric motor is required to rotate at a rate up to 3000 r/min. The design of the turbine generator plays an important role in the generator's performance. To research the relationship between different blade numbers, inlet angles and outlet angles and the performance of the generator, we use the finite element method, to model mesh, solve and analysis with different generator designs by the way of Fluid Structure Interaction of Ansys Workbench-CFX, and the design problems and some modifying advices are presented. According to the analysis results, the turbine with the inlet and outlet angular of 73° has higher rotation velocity with the fluid rate of 28~35 L/s and serious cavitations. This needs to reduce the inlet and outlet angular or the number of the vane, and increase the inner diameter of the flow tube.
